Abstract
<h3>BACKGROUND</h3> With a significant rise in the use of cone beam computed tomography (CBCT) and continuous evolution of newer applications, clinicians are increasingly using CBCT scans for bone density assessment using pixel intensity values (PIVs) while planning orthodontic treatment and in assessing fracture healing and dental implant sites. Several studies show that bone density increases with mandibular morphology and that patients with class III malocclusion have denser bone. <h3>OBJECTIVE(S)</h3> The objective of this study was to evaluate whether CBCT can determine relative differences in bone density among patients with different occluso-mandibular plane angles. <h3>STUDY DESIGN</h3> Retrospective evaluation of 300 CBCT scans of patients with different occluso-mandibular plane angles was performed. PIVs were measured with an area of 10 × 10 mm for different points of interest. The regions that were measured in the maxilla and the mandible were in the trabecular bone between the maxillary central incisors, between the first and second premolars, and mesial to the first molar, providing 6 points of interest. <h3>RESULTS</h3> The trabecular bone density between the central incisors in the maxilla was 527 and in the mandible it was 519 in the normodivergent group, 538 for the maxilla and 537 for the mandible in the hyperdivergent group, and 448 for the maxilla and 490 for the mandible in the hypodivergent group. Second premolars measured 331 for the maxilla and 408 for the mandible in the normodivergent group, 311 for the maxilla and 426 for the mandible in the hyperdivergent group, and 287 for the maxilla and 420 for the mandible in the hypodivergent group. The sites mesial to the left first molar measured 327 for the maxilla and 368 for the mandible in the normodivergent group, 285 for the maxilla and 354 for the mandible in the hyperdivergent group, and 289 for the maxilla and 389 for the mandible in hypodivergent group. <h3>DISCUSSION/CONCLUSIONS</h3> Data from this study show that PIVs are very similar in both maxillary and mandibular sites and cannot reliably discern bone density between groups with different occluso-mandibular plane angles.
